After our call, I received my B12 shipment the next day
Both pills and injections have excellent safety profiles
Treatment with high dose vitamin B12 been shown to be safe for more than 50 years Out of fear of overdosing vitamin B12, treatment is often reduced to below the frequency that is needed by the patient, or, even worse, treatment is stopped completely
B12 supports normal energy metabolism and red blood cell production, so correcting a genuine deficiency can help you feel and perform like yourself again, but shots are not a proven performance enhancer for people who are not deficient
It is not a reason to assume the worst, and it is not a cancer test
For the push, I routinely stick (pun intended) to a 23 gauge needle, though your doctor or pharmacist may have their own opinions on needle gauge or even syringe volume
